The production process of steel bars mainly includes steps such as raw material treatment, heat treatment, treatment and cutting, as well as quality inspection and packaging. Firstly, coarse steel ingots are produced by smelting in a blast furnace, and steel billets that meet the requirements are obtained through continuous casting in a continuous casting machine. Then, the steel billet is sent into the heating furnace for pretreatment to reach the appropriate processing temperature. Next, the steel billet enters the rolling mill for rolling, undergoes processes such as rough rolling and finishing rolling, and finally obtains steel bars with the required diameter. During the rolling process, steel bars also need to undergo water quenching and cold drawing treatments to achieve certain strength and diameter requirements. Finally, the steel bars need to undergo surface treatment and quality inspection to ensure that the products meet the standards before packaging.

As one of the main components of bridges, steel reinforcement can effectively improve the bearing capacity, seismic resistance, and durability of bridges. In bridge construction, steel bars are widely used in structures such as beams, slabs, and columns to ensure the safety and stability of bridges. In road construction, steel bars are mainly used for frame structures and supporting rods laid on the ground of highways, railways, and other structures. It can effectively improve the bearing capacity and durability of roads, and extend the service life of roads.
